+# squid
+
+> THIS MODULE IS OBSOLETE.
+> USE [THE PYTHON ONE](../../python.d.plugin/squid) - IT SUPPORTS MULTIPLE JOBS AND IT IS MORE EFFICIENT
+
+The plugin will monitor a squid server.
+
+It will produce 4 charts:
+
+1. **Squid Client Bandwidth** in kbps
+
+ * in
+ * out
+ * hits
+
+2. **Squid Client Requests** in requests/sec
+
+ * requests
+ * hits
+ * errors
+
+3. **Squid Server Bandwidth** in kbps
+
+ * in
+ * out
+
+4. **Squid Server Requests** in requests/sec
+
+ * requests
+ * errors
+
+### autoconfig
+
+The plugin will by itself detect squid servers running on
+localhost, on ports 3128 or 8080.
+
+It will attempt to download URLs in the form:
+
+- `cache_object://HOST:PORT/counters`
+- `/squid-internal-mgr/counters`
+
+If any succeeds, it will use this.
+
+### configuration
+
+If you need to configure it by hand, create the file
+`/etc/netdata/squid.conf` with the following variables:
+
+- `squid_host=IP` the IP of the squid host
+- `squid_port=PORT` the port the squid is listening
+- `squid_url="URL"` the URL with the statistics to be fetched from squid
+- `squid_timeout=SECONDS` how much time we should wait for squid to respond
+- `squid_update_every=SECONDS` the frequency of the data collection
+
+Example `/etc/netdata/squid.conf`:
+
+```sh
+squid_host=127.0.0.1
+squid_port=3128
+squid_url="cache_object://127.0.0.1:3128/counters"
+squid_timeout=2
+squid_update_every=5
+```
